United States Antimony (UAMY) Q4 2025 earnings review
Transformational Top-Line Growth Repositions USAC, But Execution Risk Looms
United States Antimony (USAC) is aggressively pivoting from a micro-cap processor to a heavily-funded, vertically integrated critical minerals player. Fueled by a 230% spike in antimony prices and massive structural supply deficits, FY25 revenue accelerated 163% YoY to $39.3M. However, scaling costs and a massive $7.1M stock-based compensation charge drove a $4.3M net loss. Armed with a $91M war chest from aggressive equity raises, management has secured $354M in multi-year contracts and is guiding for an explosive acceleration to $125M in revenue for FY26.
🐂 Bull Case
With China controlling ~84% of global tungsten supply and 85-90% of antimony refining capacity, USAC is positioned as a critical national security asset, bolstered by Chinese export controls driving prices up over 400% at their peak.
$354M in newly executed contracts—including a five-year sole-source DLA agreement—derisks the medium-term revenue profile and provides a clear runway for the $125M FY26 guidance.
🐻 Bear Case
The company raised over $100M via ATM and direct offerings in 2025. Common shares outstanding ballooned from 113M to 140M, heavily diluting existing shareholders to fund expansion and the $37M Larvotto stake.
Guiding for 218% revenue growth in FY26 requires flawless execution in scaling the Thompson Falls facility and seamlessly transitioning from third-party ore to internal feedstocks.
⚖️ Verdict: 🟢
Bullish but speculative. The strategic repositioning, massive contract wins, and $91M liquidity cushion are game-changers. However, the valuation requires absolute precision in scaling production to meet the aggressive $125M revenue target.
Key Themes
Unprecedented Defense & Commercial Backlog
The company locked in $354M in new antimony contracts in 2025. This includes a previously announced $245M Defense Logistics Agency (DLA) contract and a $107M commercial contract. This backlog fundamentally shifts USAC from relying on spot market sales to highly predictable, long-term contracted volume.
Gross Margin Compressing Despite Record Pricing
A significant red flag contradicts the positive pricing narrative. While FY25 gross margin improved slightly YoY (25% vs 23%), the quarterly trajectory is decelerating rapidly. Based on derived data, gross margin compressed from 34% in Q1, to 27% in Q2, 23% in Q3, and roughly 20% in Q4. This indicates that rising costs for third-party ore and facility scaling are severely outpacing record market prices.
Domestic Mining Vertical Integration
To combat margin compression and supply chain risks, USAC is aggressively pursuing self-sufficiency. Mined material from its Stibnite Hill, Montana claims is now ready for processing at the newly acquired Radersburg flotation facility. Management explicitly stated that shifting to internally mined feedstock is expected to substantially enhance margins in 2026.
Massive Balance Sheet Transformation
The company’s liquidity profile is completely reversing. Cash and investments surged from $18.2M at year-end 2024 to $91.3M at the end of 2025. This was funded by $110M in equity offerings. Capital allocation is aggressive: $27.8M in CapEx (including $17.1M for Thompson Falls expansion) and a $37.2M strategic investment for 10% of Larvotto Resources.
Heavy Reliance on International Supply (Near-Term)
Until domestic mines fully ramp up, USAC's immediate growth relies on third-party suppliers. Inventory levels skyrocketed to 465 tons (valued at $11.1M), sourced heavily from international markets. Prior quarters highlighted quality issues (e.g., high arsenic) and logistical bottlenecks from these suppliers, posing an acute risk to meeting the massive 2026 delivery targets.
Other KPIs
Accelerating. Up 219% YoY from $11.1M in FY24. The primary driver was a 230% increase in average selling price due to strong market demand and Chinese export controls. This segment completely dominates the company's financial profile.
Stable. Up 14% YoY, driven by an 8% increase in volume and a 6% increase in average selling price. While it remains a steady contributor, it has become strategically secondary to the critical minerals surge.
Decelerating profitability. Operating expenses tripled from $5.86M in FY24. A massive portion ($7.08M) was non-cash share-based compensation, alongside aggressive hiring and professional fees to support the company's rapid upscaling and capital market activities.
Guidance
Accelerating. This guidance represents an implied 218% YoY growth rate over FY25's record $39.26M. Achieving this assumes flawless execution of the $17.1M Thompson Falls smelting expansion and consistent feedstock delivery, likely heavily back-weighted as new capacity comes online.
Key Questions
Margin Compression Reversal
Despite a 230% increase in average selling prices, our data shows gross margins compressing sequentially throughout 2025, ending Q4 near 20%. What is the exact timeline for internally sourced Montana ore to reverse this trend and begin delivering the 60%+ margins mentioned in previous quarters?
Larvotto Resources Strategy
You deployed $37.2 million in cash for a 10% stake in Larvotto Resources. Given your prior acquisition proposal was rejected, is the ultimate goal a hostile takeover, or are you satisfied with a strategic supply partnership?
Throughput Bottlenecks
The $125M revenue guidance implies a massive increase in physical throughput. With the Thompson Falls expansion completing, what is the primary bottleneck to hitting 500+ tons per month—is it smelter efficiency, labor availability, or raw ore logistics?
